[time-nuts] Advantages of GNSS ???

[Glen English VK1XX]

and non monitonicity in the device is the death of a control loops.

My attempts at building good OCXOs using cheap AT crystals in the 90s 
was thwarted by.... non monotonic bending crystals !

And everytime they would wake up, the monitonicity would be in a 
different part of the control curve....

and they exhibited hysteresis, like defined steps , this seems to be the 
case with most crystals, the harder you looked, the more undesirable 
imperfections you found...
